You will find basically three types of cough medications which are used during pregnancy. These are referred to as cough suppressants, expectorants, and antihistamines. Cough suppressants suppress the need to cough, while expectorants can promote expulsion of cough by thinning the mucus. Antihistamines are often prescribed for relieving the signs and symptoms of allergy. Antihistamines that can be used while pregnant are loratadine, cetirizine, chlorpheniramine, promethazine, fexofenadine, and hydroxyzine. However, take them only under the supervision of the physician. Antihistamines can help to ease the allergic reactions like runny nose, stuffy nose and sneezing, but could also cause drowsiness.
The expectorant that’s considered safe to be used while pregnant is guaifenesin. However, this medication shouldn’t be used for a prolonged time period. Probably the most commonly used cough suppressant during pregnancy is dextromethorphan. In one animal study, medicines has been found to cause birth defect in chick embryo. However, this research is believed to be defective anyway and dextromethorphan is largely considered as safe for use by pregnant women. But still, they ought to take it only after consulting their physician.
Another drug that may be prescribed by some physicians is Sudafed, containing the decongestants pseudoephedrine and phenylephrine. Frequent utilization of these two ingredients can affect the blood flow to the placenta, and thus pregnant women are encouraged to avoid this drug for that first 13 weeks of being pregnant. The risk of birth defects brought on by these two ingredients is quite low. However this risk could be higher for ladies who smoke.
